Attack on U.S. mission in Benghazi – Attackers set the U.S. mission in Benghazi, Libya, on fire on September 11, 2012. The U.S. ambassador to Libya, Christopher Stevens, and three other U.S. nationals were killed during the attack. The Obama administration initially thought the attack was carried out by an angry mob responding to a video, made in the United States, that mocked Islam and the Prophet Mohammed. But the storming of the mission was later determined to have been a terrorist attack.

Story highlights

FBI releases photos of 3 men who were at scene of attack that killed 4 Americans

They are not being called suspects, but one source says they could be implicated

The men were not identified in posts on the FBI website

The three men who the FBI announced it is seeking information about could "possibly be implicated" in the attack on the U.S. consulate in Benghazi, Libya, that killed U.S. Ambassador Chris Stevens and three other Americans, a federal law enforcement official said Wednesday.

The official said the men were at the scene of the September 11 attack, and it is unclear if they were involved or just could have knowledge about what occurred that night.

The men are not characterized as suspects in the FBI's material, said the source, who has been briefed on the investigation. Another federal law enforcement official would only comment: "We want to talk to them."

The men "may be able to provide information to help in the investigation," the FBI said in a statement.

The FBI released pictures of the three men -- each labeled as "unknown person" -- on its website and asked people to e-mail tips to BenghaziTips@ic.fbi.gov. The photos came from surveillance video taken the night of the attack on a diplomatic facility and CIA annex.

"This is thoroughly thought out," the federal law enforcement official told CNN, adding the first step is not to just "blast out photos."
